[0035] The following detailed description is of the best currently contemplated modes of carrying out the invention. The description is not to be taken in a limiting sense, but is made merely for the purpose of illustrating the general principles of the invention, since the scope of the invention is best defined by the appended claims.

[0036] Certain terminology will be used in the following description for convenience and reference only, and will not be limiting. For example, the words upwardly, downwardly, rightwardly, and leftwardly will refer to directions in the drawings to which reference is made. The words inwardly and outwardly will refer to directions toward and away from, respectively, the geometric center of the system and designated parts. Said terminology will include the words specifically mentioned, derivatives, and similar words. Also, connected to, secured to, or similar language includes the definitions indirectly connected to, directly connected to, indirectly secured to, and directly secured to.

[0037] FIG. 1 discloses one embodiment of the present invention 10, which may be referred to as a recreational vehicle air conditioning tester 10. It may have a recreational vehicle female plug 170, such as a six pin plug 20 for compatibility with certain recreational vehicle air conditioning male plugs 140, also referred to as harnesses 140, such as many Dematic or an Advent unit.

[0038] The recreational vehicle female plug 170 may also be a nine pin plug 30 for use with other types of air conditioning male plugs 140 or harnesses 140, such as some made by Coleman company.

[0039] FIG. 1 shows the air conditioning unit 180, with the wire harness 140, also referred to as the air conditioning male plug 170 extending down from the air conditioning unit 180.

[0040] In fact, any type of female pin plug may be utilized with the present invention.

[0041] In one embodiment of the present invention 10, a power cord 80 may be operably connected thereto. When the power cord 80 is plugged into a power source, then the present invention 10 may have power to be activated.

[0042] In one embodiment, the six pin plug 20 may be operably connected to at least one of either an off/low/hi fan switch 50 or an on/off compressor switch 40. At least one of either the off/low/hi fan switch 50 or the on/off compressor switch 40 may be operably connected to at least one of either a voltage display 60 or an amperage display 70. The power cord 80 may be operably connected to at least one of either the on/off compressor switch 40 and the off/low/hi fan switch 50. The power cord 80 may be operably connected to at least one of either the voltage display 60 or the amperage display 70.

[0043] After the male plug 140 is plugged into the appropriate female plug, and after the present invention 10 is plugged in to a power source, such as a standard outlet, then the on/off compressor switch 40 or the off/low/hi fan switch 50 can be activated to display the voltage via a voltage display 60, or to display the amps via an amperage display 70.

[0044] Both the compressor switch 40 and the off/low/hi fan switch 50 may be on at the same time and the compressor and fan will be on, and the device 10 will provide a total amp draw.

[0045] FIG. 2 illustrates an embodiment of the present invention. Both the six pin plug 20 and nine pin plug 30 are illustrated as disposed on one side. Both the on/off compressor switch 40 and the off/low/hi fan switch 50 may be disposed on the top side. And both the voltage display 60 and amperage display 70 may be on the top side. The power cord 80 is illustrated as extending from the side opposite of the six pin plug 20 and nine pin plug 30. The aforementioned components may be arranged in any configuration.

[0046] FIG. 3 illustrates one embodiment of a schematic view of the present invention 10.

[0047] FIG. 3 illustrates how the six pin plug 20 may be operably connected to both the on/off compressor switch 40 and the off/low/hi switch 50. It also shows how the six pin plug 20 may be connected to at least one of either the voltage display 60 or the amperage display 70. In one embodiment the voltage display 60 and amperage display 70 is one single unit.

[0048] The power cord 80 is illustrated in FIG. 3 as having a ground, hot, and neutral plug for a standard three pronged power cord 80. However, in another embodiment, the power cord 80 may have a two-pronged plug,

[0049] FIG. 4 illustrates another embodiment of the present invention 10, having indicator lights 150 to test other conditioning components. The present invention can be used to test the junction box. The indicator lights may inform the user if everything upstream of the air conditioner roof unit is working properly, by informing the user if the roof unit is receiving a signal to turn on. The indicator light 150 may be operably connected to an indicator light plug 160. Thin indicator light plug 150 may be the same as the air conditioning male plug 140 and the same as the recreational vehicle female plug 170.

[0050] In one embodiment there may be a hi fan indicator light 153, which may be red; there may be a low fan indicator light 154, which may be green; and there may be a compressor indicator light 156, which may be blue.

[0051] It should be understood, of course, that the foregoing relates to exemplary embodiments of the invention and that modifications may be made without departing from the spirit and scope of the invention as set forth in the following claims.
